If you can get some dualing Pistols in there instead of Pistols you will be much better off.The extra +4 range (now outside most charge ranges) and the +1 to hit is a big deal.Your Marksmen can't use them though so that sucks.

If you can even toss a few on your Youngbloods you can effectivly make them BS3 and WS3. Not great but they may be able to be more help in the warband this way.

I like themed warbands, only problem is, that by limiting yourself to certain equipment and warrior types, you give your opponent an advantage without gaining any benefits. Drop pistols on marksmen and give them bows and other reasonable ranged weapons. Let CC guys act as "duelists". Also remember that pistols are one round weapons, which means your warriors are left with daggers as only weapons after you made a salvo. (btw rapiers can only by taken after a hero gains a skill to use them). I see you like blackpowder weapons (pistols) - why not trying that fan-made warband of Nuln? (don't know how it is called, don't care and don't like). You may also try Tileans - they are better suited for cc and even got henchmen group that's called well..."duellists" . All depends how liberal your gaming group is.
